"I'd say you're spoiled then"
Of course I've been spoiled by the primes and I'm going to try to add one of the 135mm f/2.0 lenses too. I don't plan on replacing the 70-200mm though. There just isn't a better zoom in low light in that range, but I don't get the "WOW" factor from it when I have to open it up in low light.
Oh, and I think I'll pass on the f/3.5 to f/5.6 consumer lenses for low light shots
. I do have a 70-300mm in that range that takes wonderful outdoor portraits, even at 70mm wide open. I highly recommend it, but just not for low light.
Here's a shot with the 70-300mm at 70mm f/4 (through glass)
Here's a shot with the 50mm f/1.4 that I normally use indoors, but was trying out a new polarizer that I received as an early father's day present.
I really like this lens for portraits too.
